Numbers /1,919
How rare is 1,919?
1,919 scores 756 and sits in the Singular tier — 1 in 3,135 of all supported numbers score this high or higher. Everything below is computed from a complete analysis of all 1,000,001 numbers in range.
RNGdle.net’s own rarity score. Top 0.03% means that proportion of supported numbers scores at least this high. Every exact number has the same chance of being rolled. Same-length rank keeps the score and compares only numbers with 4 digits, including ties. How this differs from EP · Badge guide
These notes make the number easy to read, but they add no score unless a separately counted rarity signal appears below.
Two digits alternating with period two, like 5252.
Sequence · signal frequency
A number of four or more digits built from just two digits.
Repetition · signal frequency
One of 9,000 four-digit numbers in range.
Range · signal frequency
This number's digits add up to an uncommon total.
Arithmetic · signal frequency
This number uses an uncommon count of distinct digits.
Repetition · signal frequency
The product of exactly two primes.
Factorization · signal frequency
Every comparison strictly alternates between rising and falling.
Sequence · signal frequency
Two different digits each appear twice.
Repetition · signal frequency
Strongest signal: ABAB pattern. It appears in 243 supported numbers and contributes +240 after correlation decay.
Why is 1,919 unusual? Only 0.03% of the 1,000,001 supported numbers receive an equal or higher rarity score. This number falls in the Singular tier. Scoring is grounded in the exact frequency of each detected trait — rarer traits carry more information and contribute more to the score.

Patterns in this number
Each of these has its own page explaining how common the pattern is and why.
Double Pair Numbers
A double pair has two different digits appearing twice each, like 3388 or 271721. It is the digit equivalent of two pair in poker.
Numbers Built From Two Digits
These numbers use only two different digits across four or more places, like 9119 or 303033. The whole number is drawn from a two-symbol alphabet.
ABAB Pattern Numbers
Two digits taking strict turns: 5252, 8080, 393939. The pattern repeats with period two from the first digit to the last.
Zigzag Digit Numbers
Every comparison changes direction: up, down, up, down — or the reverse. In 792619 the path is 7 < 9 > 2 < 6 > 1 < 9.
Semiprime Numbers
A semiprime is a product of exactly two primes, counted with multiplicity — 15 = 3 × 5, and 49 = 7 × 7 counts too.
